sysutils: Replace RMD160 checksums with BLAKE2s checksums

All checksums have been double-checked against existing RMD160 and
SHA512 hashes

sysutils: Remove SHA1 hashes for distfiles

Log message:
Add SHA512 digests for distfiles for sysutils category

Problems found with existing digests:
	Package memconf distfile memconf-2.16/memconf.gz
	b6f4b736cac388dddc5070670351cf7262aba048 [recorded]
	95748686a5ad8144232f4d4abc9bf052721a196f [calculated]

Problems found locating distfiles:
	Package dc-tools: missing distfile dc-tools/abs0-dc-burn-netbsd-1.5-0-gae55ec9
	Package ipw-firmware: missing distfile ipw2100-fw-1.2.tgz
	Package iwi-firmware: missing distfile ipw2200-fw-2.3.tgz
	Package nvnet: missing distfile nvnet-netbsd-src-20050620.tgz
	Package syslog-ng: missing distfile syslog-ng-3.7.2.tar.gz

Otherwise, existing SHA1 digests verified and found to be the same on
the machine holding the existing distfiles (morden).  All existing
SHA1 digests retained for now as an audit trail.

Log message:
Update sysutils/testdisk to testdisk-7.0.

Changes:
== 7.0 ==
=== General Improvements ===
Various fix including security fix, thanks to
* Coverity scan (Static Analysis of source code)
* afl-fuzz (security-oriented fuzzer).
* Denis Andzakovic from Security Assessment for reporting an
  exploitable Stack Buffer Overflow

=== TestDisk ===
==== Improvements ====
* exFAT: better support
* ext4: handle 64 bit blocks or 64 KiB blocksize. Fix detection and file
  listing

==== Bug fixes ====
* Avoid erroneous error when writing 512 bytes on hard disk using 4k sector
* FAT, NTFS: avoid NULL pointer dereference if localtime() returns NULL.
  Thanks to Graham Sutherland for reporting this bug.

=== PhotoRec & QPhotoRec ===
QPhotoRec is a Graphical User Interface (Qt based GUI) version of PhotoRec.
More user friendly, it recognizes the same file formats.

PhotoRec remains recommended for advanced users, it can stop a recovery and
resume it later, it recovers more fragmented files when brute-force technology
is enabled and expert mode is available.

==== Improvements ====
* Reduced false positives for more than 80 file formats.
* .gif: fix filesize detection
* .flv: add Flash filesize detection
* .mpg: detect filesize for MPEG
* .ra: detect filesize for RealAudio3
* Improved algorithm to deal with data fragmentation resulting in a general
  speed increased
* Speedup brute-force mode. Brute-force mode can recover more fragmented
  files, but it's still slow and not 100% reliable. You can enable it in
  PhotoRec Options menu.

New file formats recovered by PhotoRec:
* .3dm: Rhino / openNURBS
* .ari: ARRI Raw Video
* .camrec: Camtasia Studio
* .dad: Micae DVR
* .dcm: Digital Imaging and Communications in Medicine (DICOM)
* .fp12: File Maker Pro 12
* .kra: Krita
* .mlv: Magic Lantern Video
* .notebook: SMART notebook
* .ora: Mypaint
* .red: RED2 video format
* .rlv: Revelation password
* .vbm: Veeam Backup Metadata
* .woff: Web Open Font Format

Log message:
Bump all packages that depend on curses.bui* or terminfo.bui* since they
might incur ncurses dependencies on some platforms, and ncurses just bumped
its shlib.
Some packages were bumped twice now, sorry for that.

Log message:
Fixes missing buidlink with curses.
Noticed by diger in pkgsrc-users@.

Also fixes missing buildlink with libiconv and zlib.
